Sorry if I'm pointing out the obvious, but since you KNOW what her LL's are, have you considered ACTING on that knowledge? Like maybe giving her the night off... I mean REALLY off. No cooking, cleaning, dealing with kids - you take care of ALL of that. Let her put her feet up, relax, have a bath, whatever. She can read, watch TV, anything she desires. All night (evening). No demands on her at all. Would that be an Acts of Service gift?
Or how about a bunch of homemade certificates for things like cooking, cleaning, Wild Card (she gets to decide), and whenever she presents one, she gets that, no questions asked.
